'ro ALL wHoM iT 'MY eoNennN;

Be it known that I, Clin CARPENTER, ofthe city of Buffalo, in thc-countyoi Erie, and State ot' New York, have invented certain new and usefulImprovements in Apparatus for Heating4 Railroad-Cars; and I do hereby,declare that the following is a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspecification, in which- Figure I is a plan and horizontalscction of alocomotive, tender, and one car, provided with my improved apparatus.

Figure II is a vertice.y longitudinal section of the tender and car, thelocomotive being shown in elevation.

Lilie letters of reference designate like parts in both figures.

To avoid the use of stoves in the various cars forming a railroad-train,has lcd to the invention of a nuu1 ber of devices for heatngithe,cars-by means of hot-air or steam. The employment of steam isobjectionable on account of the danger Lesulting from the escape of thesteam in case of an accident breaking or-rupturing the pipes conductingit tothc diferent cars.

*F* VTheemploynzient of h'tb'air t'or warmingtho cars requires a fan orother blower to t'oree the airtli'rough `the conducting-pipes, whichapparatus is operated by mechanism connecting` with the axle of the carwhen in motion. In case of a stoppage or detention of the train, by snowor other cause, some other means become necessary to maintain thepropertemperature, as the air-forcing apparatus ceases to operate when thecars arc at rest.

My invention is designed to obviate these diiiicultios; and theinvention consists- First, in the combination and arrangement'of anapparatus, by means of which either or both steam and hot air can beemployed, the steam being used when the train is at rest, and when nodanger need be apprehended from its employment. i

Second, in the arrangement and method of operating the fan-blower, whichprevents the springing action of the body of the car from interruptingor deranging the motion of the fan, all ashereinafter fully set forth.

In the drawings, A is the locomotive, B the tender, and C a car coupledthereto. D is a stove or furnace arrangediu the tender for heating theair. E is a fan, of any suitable construction, for forcing the airthrough the heater and conducting-pipo. F-is the conducting-pipe,leading from the coil in the heater through the dfferent ears. g is n.triple-jointed coupling for said pipe, between the cars, although anysuitable coupling that will yield with the relative movement of the carsmay be employed. H represents one or more branch-pipes, leading from themain pipedown the side of the car, and terminating in a register orregisters I,j being a valve for regulating the escape of the air fromsaidv pipe. .H, I,and j represent a corresponding pipe, register, andvalve, for the steam when itis employed, the register or radiator Idiffering from I in being made tight, to prevent the escape of the steaminto the car. K is a. steam-pipe, leading from the boiler and openinginto the nozzle ot the air-pipe before it enters the heater, as shown.This pipe is provided with a suitable jointed or flexible coupling, g',between the locomotive and tender. A

The fan is operated by a belt, m, on a pulley, n, on one of thecanaxles, connecting with a pulley, o, mounted in pendant-hearings fromthe body of the car. From this latter pulley a belt, p, extends upwardthrough the bottom of the car, and around the pulley g onY tho fanshaft.A loosepulley, r, may also be employed on the fan-shaft, to which thebelt p can be transferred in regulating the temperature et" the cars. Bythe use and arrangement of the two belts, m12, the operation of the fanis not affected by they springing or vertical movement-of the body ofthe car, as the fan-shaft and pulley o maintain an unvarying distancefrom each other, while the vertical motion oi the body of the car, towhich the hearings of pulley o are attached, only nominally variesl thedistance between the latter' and the ear-axle with which the belt mconnects, so that the operation of the belt is not aiiected thereby.This arrangement, or somo equivalent means, is necessary, inorder toactuate the fan from the car-axle.

The operation of my improvements, thus constructed and arranged, is asfollows:

When the train is in motion, the steam-pipe is closed, or nearly so, andthe fan set in motion, which forces the air through theheater-conducting pipe and register into the dierent cors. A smallamount of steam may be admitted into the air to render it properlymoist, which makes it more agreeable to those inhnling it in the cars.'

In case of a detention of the cars from any cause, the air-pipe near thefan may be closed by n. vulve, s, und the air-pipes H by the valves j,while the vulve j being opened, steam is forced through tho coil in theheater and into the radiators I of the different cnrs, thus maintainingthe proper temperature of' the Same.

Without some such provisionrextremo sulering would ensue in cases oflong detention of the train by snow-tlrifts or other obstructions. Italso becomes necessary in heating the cars a5 the dierent stations,before the train is put in motion.

By means'of my arrangement, the same conducting-pipe can be employed forboth the steam and hot air; and th'e change from the use of the one tothe other eiected in the simplest marmer. In hot weather, the fan andconducting-pipes can be employed in Ventilating the cars.

' I do not claim the employment of steam or hot air in heatingrai1roadcors, nor an apparatus for the use of either alone.

What I claim as my invention, and `desire to secure by Letters Patent,is-

The combination und arrangement of the steam-pipe K, fan E, valve S,furnace D, conducting-pipe F,

branehes H H provided with vnlvesjj, and register and radiator I I',adapted for the use of steam und hot4 air alternately or together inheating a. train of cars, substantially in the manner s et forth.
